Moving the U.S. embassy in Israel from Tel Aviv to Jerusalem may have been one of President-elect Donald Trump’s campaign promises, but experts and Palestinian officials are warning of serious consequences if he follows through.

“The US president-elect’s choice to be the next American ambassador to Israel, David Friedman, has promised to move the US Embassy to Jerusalem from Tel Aviv as a symbol that the United States considers Jerusalem the eternal and undivided capital of Israel. Eight American presidents refused to take this step and kept the embassy in Tel Aviv to avoid prejudicing the outcome of negotiations on the future of Jerusalem between the warring parties. It will be a major shake-up in American policy if the new administration follows through on the plan,” writes Bruce Riedel

“Much has been written about the views of David Friedman, President-elect Donald Trump’s nominee as the next U.S. Ambassador to Israel. We have compiled this collection of quotes from his articles and speeches, so people can better understand and judge Mr. Friedman’s views, based entirely on his own words,” writes Lara Friedman

The appeal follows a deal struck on Sunday after weeks of discussions trying to assuage settler anger over the mandated evacuation, when the government said the settlers could be moved to a nearby hilltop to lease was is ostensibly absentee property that has been abandoned by its owners.

Palestinian residents of the Jordan Valley regularly face evacuations and interruption due to Israeli military exercises on or near their land. The district of Tubas, meanwhile, is one of the occupied West Bank’s most important agricultural centers.
